본고안은 재봉기의 급유 및 환류장치에 관한것으로서, 특히 급유장치와 환류장치를 일체로 하여 구조를 간단히 할 수 있을 뿐만아니라, 높은 효율을 얻을 수 있도록 한 것이다.The present invention relates to a lubrication and reflux device of a sewing machine, and in particular, the lubrication device and the reflux device are integrated to simplify the structure and to obtain high efficiency.
종래에는 재봉기의 급유장치 및 환류장치는 제 1 도 내지 제 3 도에서와 같이 분리 설치하여, 급유펌프(34)는 세운축(32)에 의한 구동방식에 의해 작동하고, 그 급유펌프(34)의 펌프구조는 제 2 도에서와 같이 하단에 임펠라(37)가 부착된 임펠라샤프트(36)에 의해 본체(31)의 각 부분 훅, 바늘대, 실체기 바늘대와 부싱등에 윤활율을 공급하였다.Conventionally, the oil supply device and the reflux device of the sewing machine are separately installed as shown in FIGS. 1 to 3, and the oil supply pump 34 operates by the driving method by the upright shaft 32, and the oil supply pump 34 As shown in Fig. 2, the lubrication rate was supplied to each of the partial hooks, the needle bar, the actual machine needle bar, and the bushing of the main body 31 by the impeller shaft 36 with the impeller 37 attached to the lower end as shown in FIG.
그리고, 환류펌프몸체(35)의 구성은, 제 3 도에서와 같이 상부에 횡으로 설치된 구상축(33)에 별도의 편심(43)을 가공하여, 이 편심(43)의 회전에 의해 바늘대부에 공급 윤활유를 환류하도록 구성되었다.In the constitution of the reflux pump body 35, as shown in FIG. To reflux the supply lubricant.
이와같은 종래의 구성은 급유장치와 환류장치의 세운축과, 상축에 별도의 부품으로 분리 설치되어 있어, 구조가 복잡할 뿐만아니라, 환류장치의 구조가 플런저 타입의 펌프로서, 부품제작이 난이하여 조립설치시, 고도의 숙련이 요구되며, 효율이 저하되는 문제점이 야기되었다.Such a conventional structure is separately installed in the upright shaft of the oil supply device and the reflux device and the upper shaft, and the structure is not only complicated, but the structure of the reflux device is a plunger type pump, which makes the parts difficult to manufacture. When assembling and installing, a high level of skill is required, resulting in a problem of lowering efficiency.
본고안은 상기한 종래의 문제점을 해결하기 위하여 안출된것으로서, 본고안의 목적으로는, 급유장치와 환류장치를 일체화하되, 급유장치는 밴펌프로되고, 환류장치는 내접기어 펌프로 형성하여 부품제작을 간편용이하게 함과 함께 설치를 용이하게 하고, 효율을 향상시키려는 것이 특징이다.The present invention has been devised to solve the above-mentioned problems. For the purpose of the present invention, the oil supply unit and the reflux unit are integrated, the oil supply unit is a van pump, and the reflux unit is formed by an internal gear pump to manufacture parts. In addition to making it easy to install and to improve the efficiency is characterized.
상기의 목적을 달성할수 있는 본고안을 첨부된 도면에 의하여 상세히 설명하면 다음과 같다.When described in detail by the accompanying drawings that can achieve the above object as follows.
제 4 도 및 제 5 도에 도시한 바와같이, 본체(1) 내부에 세운축(2)과, 상축(3)을 설치하되, 급유펌프(4)와 환류 펌프몸체(5)에 의해 본체(1) 선단의 바늘대 및 부싱에 윤활유를 공급 또는 환류하는 재봉기(M)에 있어서, 상기 세운축(2)의 하단에, 임펠라가 일체로 된 임펠라샤프트(6)를 내장설치한후, 보조판(7)을 취부하여 급유펌프덮개(8)를 조립한 급유펌프(4)를 설치한다.As shown in FIG. 4 and FIG. 5, the upright shaft 2 and the upper shaft 3 are provided inside the main body 1, and the main body (not shown) is provided by the oil supply pump 4 and the reflux pump body 5. 1) In the sewing machine (M) for supplying or refluxing lubricating oil to the needle bar and the bushing at the tip, an impeller shaft (6) having an integrated impeller is installed at the lower end of the upright shaft (2), and then the auxiliary plate (7). ) And install the oil supply pump (4) in which the oil supply pump cover (8) is assembled.
이때, 임펠라샤프트(6)는 급유펌프(4) 상측으로 일정거리 돌출되게 하고, 임펠라샤프트(6) 하측은 결합면(11)이 형성되게 한다.At this time, the impeller shaft 6 is protruded a predetermined distance to the upper side of the oil supply pump 4, the lower side of the impeller shaft 6 to form a coupling surface (11).
그리고, 상기 임펠라샤프트(6)에는 환류펌프몸체(5)를 축설하되, 이 환류펌프몸체(5)의 내부에는 기어가 내접되게 환류기어A(13)와 환류기어B(14)를 내장 설치하되, 환류기어B(14)의 축공(15)에는 결합면(16)을 형성하여, 상기 임펠라샤프트(6)의 결합면(11)과 긴밀히 접촉되는 상태로 결합하여 환류펌프 덮개(10)를 설치한 후, 취부브라켓(17)을 취부하여 세운축(2)의 회전에 의해 급유와 환류를 동시에 할 수 있도록 구성된 것이다.In addition, the impeller shaft 6 has a reflux pump body 5 installed therein, and a reflux gear A 13 and a reflux gear B 14 are internally installed such that gears are inscribed inside the reflux pump body 5. , The coupling hole 16 is formed in the shaft hole 15 of the reflux gear B 14, and the reflux pump cover 10 is installed by being coupled in intimate contact with the coupling surface 11 of the impeller shaft 6. After that, the mounting bracket 17 is mounted so that refueling and reflux can be performed at the same time by the rotation of the upright shaft 2.
이와같이 구성된 본고안은 본체(1)의 세운축(2)이 회전하면, 임펠라샤프트(6)가 회전되므로 임펠라샤프트(6)의 임펠라에 의해 윤활유를 급유하게 되므로서, 재봉기(M)의 본체(1)와 각 부분으로 윤활유를 공급하게 되는 것이 다.In this configuration, the impeller shaft 6 is rotated when the upright shaft 2 of the main body 1 rotates, thereby lubricating oil by the impeller of the impeller shaft 6, and thus the main body of the sewing machine M ( Lubricant is supplied to 1) and each part.
그리고, 상기 윤활유 급유시 임펠라샤프트(6)의 회전력이 임펠라샤프트(6) 상측에 환류펌프몸체(5)의 내부에 내접 설치된 환류기어A(13)와 환류기어B(14)를 회전시켜, 본체(1) 선단의 바늘대 및 부싱에 과다하게 공급된 윤활유를 환류하게 되는 것이다.In addition, when the lubricating oil is supplied, the rotational force of the impeller shaft 6 rotates the reflux gear A 13 and the reflux gear B 14 which are internally installed inside the reflux pump body 5 on the upper side of the impeller shaft 6, thereby causing the main body to rotate. (1) The lubricant supplied excessively to the needle bar and the bushing at the tip is refluxed.
이때, 상기 환류기어B(14)는 환류기어B(14)의 축공(15)에 형성된 결합면(16)과 임펠라샤프트(6)의 결합면(11)이 긴밀히 접촉되어, 완벽한 회전이 이루어져 환류효율이 증대되는 것이다.At this time, the reflux gear B 14 is in close contact with the engaging surface 16 formed in the shaft hole 15 of the reflux gear B 14 and the engaging surface 11 of the impeller shaft 6 to be in perfect rotation, and reflux. Efficiency is increased.
이상과같이 본고안은 급유펌프와 환류펌프몸체를 임펠라샤프트에 일체화하여 조립하므로서, 조립이 간편용이하여 생산비가 저렴하고, 또한 상기 환류펌프의 구조를 환류기어A와 환류기어B를 내접되게 축설하여 환류효율을 가일층 향상시키는 것이다. 즉, 종래에는, 환류펌프가 구동축에 부착되어져 구동축 1회전당 환류펌프로 1회전 작동하였으나, 본고안은 재봉기의 구조상 구동축 1회전당 세운축이 1.5회전되므로서, 세운축에 축설된 펌프자체의 효율이 우수할 뿐만아니라, 같은 속도에서 1.5배의 성능이 향상되는 매우 유용한 고안이다.As described above, this proposal integrates the oil supply pump and the reflux pump body into the impeller shaft and assembles them, and is easy to assemble, and the production cost is low. It is to further improve the reflux efficiency. That is, conventionally, a reflux pump was attached to the drive shaft and operated one revolution with a reflux pump per rotation of the drive shaft. However, the present design has a structure of the sewing machine, in which the upright shaft is rotated 1.5 times per rotation of the drive shaft. Not only is it efficient, it's also a very useful design that offers 1.5 times the performance at the same speed.
